ICP RAID Console
Save Information
- to create a complete protocol file of the current RAID subsystem
including all settings of the ICP RAID controller and the drives. This file can be used
for remote diagnosis.
10.6.1
View Statistics
The
View Statistics
menu (
Figure 10-106
) display the performance of the drives and their
corresponding level of hierarchy. The throughput of the drives is displayed in KB/s
(Kilobytes per second) and IO/s (I/O’s per second, number of I/O’s on the controller). The
performance figures reflect the load on the controller and not necessarily the maximum
performance the controller can deliver.
Figure 10-106. View Statistics Menu
When viewing the
Host Drives
,
Logical Drives
and
Physical Drives
statistics for a
particular RAID level, ICPCON displays a list of all drives within the selected drive level
hierarchy. See
Figure 10-107
for an example of the
Physical Drives
statistics. In addition
to the performance report on the drives, the menu monitor displays the hard disk I/O
channel, hard disk ID, hard disk name and hard disk gross capacity (where 1MB =
1024KB). The figures shown at
TOTAL
represent the performance of all drives of the
corresponding hierarchy level.
Press the left arrow and right arrow keys to change the scale of the graphical KB/s
indication. Press the up arrow and down arrow keys to scroll the screen to see additional
drives (if available).

Use
Cache Statistics
to view the utilization of the ICP RAID controller’s caches, (read
cache and write cache). This option also displays the size of the cache in KB and the
settings of both caches (on or off). The figures for “cache hits” show how often requests
can be serviced out of the cache, for example, without triggering an immediate disk IO.
